Photosynthesis has attracted the interest of scientist for many years. This curiosity is understandable given the great importance of the process to life on earth. A large body of knowledge exists about photosynthesis and this is organized into it's own chapter.

In the context of this chapter, just remember that photosynthesis is another type of metabolism that many life forms employ. Photosynthesis can be divided into two separate areas the light reactions and the dark reactions.

  • The light reactions take photons and convert them into high potential electrons that then fall down an ETS. The eventual result being ATP and NAD(P)H for the synthesis of macromolecules and growth.

  • The dark reactions involve using the generated ATP and NADPH to form cell carbon from CO2. This involves use of the Calvin cycle.

For more information go to the photosynthesis chapter in this textbook, which unfortunately is not ready yet.
